Hey Shawn... To be honest with you I do own a ph pen but I never use it. It stays on stand by. I have been growing for over 16 years and never got into worrying a whole lot about ph, ec, or ppms... But to each his own. I have just learned to watch my plants and give them what they ask for.
I have 21 clones in 5 gallon grow bags under 4000 watts. They are in promix with added perilite and some dolomite lime. I feed them Sen So Bloom at 3/4 dose about every 2 to 3 days (every watering they get fed). I keep slightly burnt tips but at the same time I know they are getting their maximum nutrient uptake. Along with the a&b, they also get 3ml big bud one watering, then the next they get 5 to 6ml. Not only are they handling these heavy feedings well but they are also getting other things as well. My basic feeding consists of this. And this is per gallon btw....
3/4 strength Sensi a&b
3 to 6ml Nirvana
3 to 6ml Big Bud
3 to 4ml B52
1/4 tsp of Open Sesame
3 to 6ml of Cal-Mag
1 tbsp Budswell
A "dash" of molasses
-1ml of true blooms (twice a week) via root feeding and then twice a week I hit them with 1ml via foiliar.
Then once a week they get 5ml of Earth Juice catalyst...
This sounds like a lot and it really is. But This is what my girls so want and This is what they respond best to. I actually find it all quiet simple, but then again I spend around 4 hours each night with my girls...
As you can see they stay healthy...
